What should I do if oppo r9 information cannot be sent out?

Oppo r9 information cannot be sent out for the following reasons.

1. Check whether the mobile phone is in flight mode, and eliminate the problem of setting the mobile phone, which makes the SMS unable to be sent. Open the phone settings, and the first option at the top is "airplane mode".

2. Find out whether the following mobile phones are in arrears through the operator. If the mobile phone is in arrears, the SMS will return to normal after payment.

3. Correct the number of the information center, open the phone settings and find the "Information" option.

Click the Advanced option.

Select "Information Center Number".

Write down your own information center number, and then compare it with similar local cards or consult the operator to confirm the information center number. Correct the center number of your mobile phone, and it will return to normal.

4. Back up the important files and information in the mobile phone, and try to restore the mobile phone. Open the settings and select "Restore Phone" in more settings.

5. Back up the important files and information in the mobile phone and restore the factory settings of the mobile phone.

6. If the above methods fail to solve the problem that the mobile phone can't send short messages, it may be that there is something wrong with the hardware of the mobile phone. I suggest you take the valid ticket of your mobile phone to the after-sales office for inspection and maintenance.
